Breaking a novel image encryption scheme based on improved hyperchaotic sequences
Chengqing Li, Yuansheng Liu, Tao Xie +1
Recently, a novel image encryption scheme based on improved hyperchaotic sequences was proposed. A pseudo-random number sequence, generated by a hyper-chaos system, is used to dete…
Breaking a chaotic image encryption algorithm based on modulo addition and XOR operation
Chengqing Li, Yuansheng Liu, Leo Yu Zhang +1
This paper re-evaluates the security of a chaotic image encryption algorithm called MCKBA/HCKBA and finds that it can be broken efficiently with two known plain-images and the corr…
Breaking an image encryption algorithm based on chaos
Chengqing Li, Michael Z. Q. Chen, Kwok-Tung Lo
Recently, a chaos-based image encryption algorithm called MCKBA (Modified Chaotic-Key Based Algorithm) was proposed. This paper analyzes the security of MCKBA and finds that it can…
